Title: Improvements in or relating to the production of tapered reinforced concrete posts and poles and like tapered objects
IPC: B28B23/18
Filed: 1944-10-02
Abstract: The posts &c. are moulded with the reinforcing wires tapered, i.e. inclined toward one another in the direction of taper of the posts, by the following method:- The wires are arranged in long lines above a track on which a series of moulds can run, and a tapered trough-shaped mould having slotted end plates is assembled around the wires at a filling point.  (The slots in the narrow end plate are closer together than the slots in the wide end plate). The mould is then filled with concrete and moved along the track and along the wires, narrow end foremost, to the place where the concrete is to set and harden.  Another mould is similarly assembled and filled, but this time with the wide end foremost, and then moved along the track and wires to a position adjacent the first mould.  These operations are repeated until a series of moulds is arranged alternatively with the taper in opposite directions, the concrete is allowed to set and harden, the moulds are dismantled and the exposed parts of the wires are cut.  The wires may be originally arranged parallel at the narrow spacing, and a wire-splaying device may be used to expand the wires into the slots in the wide end of the mould.  Transverse reinforcements such as annular or rectangular bands may be secured in recesses in the moulds.  Holes may be made by core pins. Specifications 571,976, [Group III], 572,385, 572,387, 572,391 and 581,815, 581,827 and 581,828, [all in Group X], are referred to.

Patent GB-182820-A (GB)
IPC: C08B3/10
Filed: 1921-03-09
Abstract: Cellulose butyrate is prepared by subjecting cellulose impregnated with a catalyst to the action of an acylating-bath containing butyric anhydride and butyric acid.  The cellulose may be impregnated with the catalyst before or during the butyrating process.  Impregnation with the catalyst may be carried out in the presence of a carrier such as acetic acid, or butyric acid preferably containing a small proportion of water and to which has been added a solvent such as methyl, ethyl or butyl alcohol, acetone, diacetone alcohol, or ethyl acetate, to prevent the separation of the bath into layers.  After impregnation the excess of the bath is removed by pressing, and the moist mass then treated with the butyrating-bath which preferably contains 465 parts of butyric anhydride and 400 parts of butyric acid; the reaction is allowed to proceed until a butyrate of the desired solubility is obtained; in certain cases the reaction is accelerated by the addition of a further quantity of sulphuric acid after the product shows a solubility in chloroform, the reaction being continued until a product soluble in alcohol-benzene is obtained.  The butyrate is soluble in alcohol-benzol, acetylene tetrachloride, acetone, ethyl acetate, carbolic acid, hot alcohol and benzol, alcohol-carbon tetrachloride, and hot solvent naphtha; and it may be employed in the manufacture of plastics, transparent sheets and films, artificial silk, lacquers, dopes, and artificial leather.

Abstract: 884,512. Valves. BRITISH THERMOSTAT CO. Ltd. June 2, 1958 [June 18, 1957], No. 19182/57. Class 135. [Also in Group XIII] An expansion valve for refrigeration systems comprises a pair of coaxial bellows 11, 12, the space between which is connected by a capillary tube 5 with a thermal feeler and the free ends of which, sealed to a plate 14, actuate a valve member 6 which is mounted in a cage 16 loaded by a range-adjusting spring 8 which is adjustable by a screw 9. The valve member coacts with a seat 7 held in place by a screwed retaining ring 18. The bellows assembly is also responsive to the refrigerant pressure in the outlet of the valve and may be arranged to be responsive to that pressure only and not to temperature. In a modification the valve member is extended upwardly to a point above the bellows assembly where it coacts with a seat in a member that is surrounded by a tube from which six separate outlet pipes lead. In this arrangement the valve-controlled passages do not communicate with exterior of the bellows assembly, and a separate connection for subjecting the assembly to refrigerant pressure is provided in the housing. In another embodiment, also in which the valve controlled passages are isolated from the bellows assembly the latter is subject to the temperature of refrigerant passing through a second passage having an inlet and an outlet to the housing.

Title: Improvements in or relating to start stop telegraph apparatus
IPC: H04L17/02
Filed: 1936-07-11
Abstract: 476,123. Type-printing telegraphy. GRIFFITH, R. G. July 11, 1936, No. 19252. [Class 40 (iii)] A start-stop transmitter is provided with means for transmitting for observation purposes continuous current reversals from the contacts which normally transmit the code signals. As shown, Fig. 1, combination bars 1a .. 1e set by a keyboard or a perforated tape are associated with actuating levers 2a .. 2e in such a way that a displaced bar lifts its corresponding lever to bring a projection 19 into the path of a cam 18a .. 18e. On engagement by the cam, the lever rocks member 4 which in turn rocks a bell-crank 7 to move a shaft 21 so that cam 20 controls levers 23, 25 instead of levers 22, 24 to operate transmitting contacts 26 in the appropriate direction. In order to send continuous reversals, the rocking of a frame 34 by a finger piece 36 lifts a further lever 42 to bring its projection 19 into the path of a seven-lobed cam 43, disengages the start-stop control latch 11 from member 12 to permit continuous rotation of cam shaft 10, lowers stop-signal transmitting lever 32 to disengage it from cam 31, and by engagement of plate 3 with down-turned ends 45 restores any displaced combination bars. Since the cam shaft 10 makes a half rotation for each complete code signal, a complete rotation corresponds to fourteen signal elements and the seven pairs of reversals produced by cam 43 will produce fourteen similarly-timed signals, alternately positive and negative or current and non- current. In apparatus in which the cam shaft makes a complete revolution for each code signal, the cam 43 may be mounted on a separate shaft geared to rotate at half the speed of shaft 10 or, as shown in Fig. 2, two cams 51, 52 with three and four lobes respectively, may be employed, the cams being rendered operative alternately by further complementary cam members 61, 62 controlling through crank arms 64, 65 the alternate lifting of levers 66, 67 by slide arms 57, 58. During code-signal transmission, with frame 34 in normal position, arms 57, 58 are rendered inoperative against the action of springs 59, 60 by a member 54. The angle between lobes 51a and 51d may be one and a half times that between any other two adjacent lobes in the two cams taken together to simulate the continental code employing a longer stop-signal. The continuous reversals may operate a meter, such as a centre-zero milliammeter, or a cathode-ray tube. Specification 439,745 is referred to.

Abstract: 189,086. Pein, E. J. von. Nov. 18. 1921, [Convention date]. Sheet-feeding arrangements.- A cash register or like machine of the kind having means for printing details twice on an inserted slip which is severed to provide a stub adapted to be filed in the machine, comprises the following slipfeeding apparatus. Between the two printings, the inserted strip is fed farther into the machine by a knurled roller 111 co-operating with a tension roller 125. A cam 101, on a shaft 100 revolving once at each operation of the machine, drives pitman 104 slotted to engage a bolt 116 and drive a bell-crank lever 113 loose on a shaft 108 and carrying at its other end a segment 114. Fast on the shaft 108 is an arm 109 carrying a shaft 110 which has keyed to it the roller 111 and a pinion 112 meshing with the segment 114. Pivoted to arm 109 is an arm 119, one end of which co-operates with a pin 118 on roller 111 to prevent overthrow of the latter, and the other end being bent under arm 109 and having a set-screw 120 for adjustment. Also keyed to shaft 108 is another arm 200 pivoted to a pitman 201, having a roller 204 moving in a race 205 on the left hand face of cam 101. Rotation of cam 101 thus causes the knurled roller 111 to be raised and afterwards rotated to feed the slip into the machine for the second printing.
